Ultrafiltration as a Method for Concentrating Rift Valley Fever Virus Grown in Tissue Culture
AUTOR(ES)
Klein, Frederick
RESUMO
Filtration by means of a Diaflo ultrafilter was used to concentrate three 1,000-ml lots and one 3,000-ml lot of tissue culture-grown Rift Valley fever virus. Quantitation of both infectivity and total protein was achieved. Water treatment with continued ultrafiltration of the virus concentrate provided a final virus product approximately 99.25% free of low-molecular-weight materials originally present in the growth medium.
